3. What are the Prerequisites for Programming a 2020 GMC Terrain Key Fob?

Before starting the key fob programming process, ensure you have the following:

Your 2020 GMC Terrain.
The Key Fob to Be Programmed: Ensure it is compatible with your vehicle.
Working Key Fobs (if available): Having two working key fobs simplifies the process.
Vehicle Owner’s Manual: Consult your manual for specific instructions.
Access to the Vehicle: Ensure you can access the driver’s seat and ignition.

4. How to Program a 2020 GMC Terrain Key Fob with Two Working Key Fobs?

If you have two functioning key fobs, the programming process is relatively straightforward.

4.1 Step-by-Step Instructions

Gather Your Key Fobs: Ensure you have both working key fobs and the new key fob you want to program.
Enter Programming Mode:
- Insert the key blade from one of the working smart keys into the driver’s door lock cylinder.
- Turn the key counterclockwise to the unlock position five times within 10 seconds. Some models may require removing the lock cylinder cap on the driver’s door handle.
- The Driver Information Center (DIC) will display “READY FOR REMOTE #2, 3, 4, etc.”
Program the New Key Fob:
- Place the new smart key into the transmitter pocket. This is usually located inside the center console storage area for Cadillac vehicles or in the front cupholder for Chevrolet, GMC, and Buick vehicles.
- Press the ENGINE START/STOP button.
- When the new smart key is recognized, the DIC display will show that it is ready to program the next key.
- Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the remote.
Program Additional Key Fobs (if needed): Repeat Step 3 for any additional key fobs you want to program.
Exit Programming Mode: Press and hold the ENGINE START/STOP button for approximately 12 seconds to exit the programming mode.

4.2 Tips for Successful Programming

Read the Instructions Carefully: Before starting, read the entire procedure to understand each step.
Ensure Key Fob Compatibility: Verify that the new key fob is compatible with your 2020 GMC Terrain.
Battery Condition: Make sure the batteries in all key fobs are in good condition.

5. How to Program a 2020 GMC Terrain Key Fob Without Two Working Key Fobs?

If you have only one working key fob or none, the programming process is more involved and takes approximately 30 minutes.

5.1 Step-by-Step Instructions

Prepare the Vehicle: Ensure the vehicle is off and all key fobs (existing and new) are with you.
Enter Programming Mode:
- Remove the key blade from your existing or new smart key.
- Insert the emergency key blade into the driver’s door lock cylinder.
- Turn the key counterclockwise to the unlock position five times within 10 seconds. On some vehicles, you may need to remove the lock cylinder cap on the driver’s door handle to access the door lock.
- The Driver Information Center (DIC) will display “READY FOR REMOTE #2, 3, 4, etc.”
Wait and Repeat:
- Wait for 10 minutes until the DIC displays “PRESS ENGINE START BUTTON TO LEARN” and then press the ENGINE START/STOP button. The DIC display will again show “REMOTE LEARN PENDING, PLEASE WAIT.”
- Repeat Step 3 two more times. After the third time, all previously known smart keys will no longer work with the vehicle. The DIC display should now show “READY FOR REMOTE #1.”
Program the New Key Fob:
- Place the new smart key into the transmitter pocket (inside the center console storage area for Cadillac vehicles or in the front cupholder for Chevrolet and Buick vehicles).
- Press the ENGINE START/STOP button.
- When the smart key is recognized by the vehicle, the DIC display will show that it is ready to program the next smart key.
- Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the smart key.

Proximity Sensors: Some key fobs use proximity sensors to automatically unlock your doors as you approach the vehicle and lock them as you walk away, ensuring convenience and security.
Two-Factor Authentication: This feature requires a secondary form of verification, such as a PIN, to start the car, adding an extra layer of security.

20. How do Security Systems Interact with Key Fob Programming?

Secure Communication: When you program a key fob, you’re essentially teaching your car to recognize this signature. This process requires secure communication to prevent unauthorized access.

Arming and Disarming: Key fobs arm and disarm the alarm system. Programming ensures that only authorized users can control these functions.
Panic Button: The panic button on your key fob triggers the alarm, attracting attention in emergencies.
